Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Development of a Sustainable Biocatalytic Process for Geranyl Benzoate Production Using Immobilized Lipase

ChemistryOpen, EarlyView.
This study optimized solvent‐free geranyl benzoate production using Lipozyme 435, achieving 72% conversion in 6 hours. Open reactors improved yields (>99% in 48 hours) by removing inhibitorymethanol. Methyl benzoate reduced enzyme activity by 54%, though Lipura Flex showed better resistance. Human cell tests confirmed no cytotoxicity.

Optimizing Processing and Formulation Strategies for Enhanced Thermal and Chemical Stability of Meltblown Polyphenylene Sulfide Nonwovens

Polymer Engineering &Science, EarlyView.
PPS/PEI alloy fibers fabricated via meltblowing exhibit enhanced thermal stability with less than 10% shrinkage at 180°C, superior chemical resistance, and a high LOI of 34. ABSTRACT Polyphenylene sulfide (PPS) meltblown nonwovens are attractive for high‐performance filtration and protective applications owing to their intrinsic chemical resistance ...

Turbulent effects on the flame behavior of turbulent counterflow nonpremixed flames

Turbulent effects on the flame behavior of turbulent counterflow nonpremixed flames
The flow field of the turbulent counterflowing stream with and without nonpremixed flames, and the behavior of diffusion region of turbulent nonpremixed flames have been investigated experimentally. The turbulent characteristics of each side flow in a counterflowing stream would be regarded as keeping their initial turbulent characteristics from one ...
